Aim Haemorrhoidal disease (HD) is a frequently occurring disorder with a significant negative impact on a patient's quality of life. Here, we describe the development and validation of the Dutch patient reported outcome measure‐haemorrhoidal impact and satisfaction score (PROM‐HISS). Methods The development of the PROM‐HISS followed recommended guidelines. Face and content validity, structural properties, reliability and construct validity were evaluated in a HD population. Reliability was tested by assessing the test‐retest reliability, defined by the intraclass correlation coefficient (ICC), and internal consistency measured with Cronbach's alpha. Construct validity was evaluated using confirmatory factor analysis (CFA) and hypotheses testing. Results The PROM‐HISS consists of three domains: (1) HD symptoms (blood loss; pain; prolapse; soiling; itching), (2) impact of symptoms on daily activities, and (3) satisfaction with treatment. The PROM‐HISS showed good face and content validity. The PROM‐HISS was completed by 102 patients (65% male), with a mean age of 58 years (23–81 years). The ICCs of the different items in the domain HD symptoms ranged between 0.56 and 0.79 and were interpreted as good. The Cronbach's alpha value was 0.80 and considered satisfactory. The CFA provided further evidence for construct validity with a good model fit. A high score on the symptoms of HD correlated with a high impact of HD on daily activities (Pearson's r = 0.632, p < 0.01) and a low degree of satisfaction (Pearson's r = 0.378, p < 0.01). Conclusion The PROM‐HISS is a reliable and valid instrument to evaluate symptoms of HD, impact on daily activities and satisfaction with treatment.
